Granted: 1991-10-29
Abstract: ABSTRACT OF THE DISCLOSURE:           An improved bolt lock with a selectively variable actuating axis depth, wherein the driving tail has formed on it two pairs of projections facing one another in each pair, each pair being situated a different distance from the front of the lock, while the guide casing, which secures the tail by its side edges, has cut out on each face a large trans-verse window which surrounds the two pairs of projections. The casing has three transverse real apertures whose centers are in line with its center line.  The arrangement is com-pleted by two selectable plane backing members which have apertures which are bushed or extended transversely by bushes, their axes being situated to coincide with the apertures in the casing.  The members also have a cutout in the form of a circular sector situated selectively to coin-cide longitudinally with the operative area of one of the two pairs of projections on the driving tail.  The whole arrangement is such that when one or the other of the two selectable backing members is selected and positioned with its bushes introduced into the apertures in the casing, the actuating axis depth or distance existing between the front of the lock and the axis of the transverse actuating mem-ber normally used will be selectively varied.

Title: Fault protection apparatus for traction motor circuit
Inventor: MELOCIK GRANT C
IPC: H02H7/08
Filed: 1987-04-29
Granted: 1991-03-05
Abstract: Abstract of the Disclosure Fault Protection Apparatus For Traction Motor Circuit Motor control circuits having fault protection devices are in commerical use today.  Such devices typically include logic elements requiring a conditioned power supply, and are incapable of operation directly from the main motor power supply. The subject apparatus includes a timing circuit for monitoring the electrical conduction of a power switching element associated with an electrical motor. The apparatus produces a fault signal in response to the power switching element continuing to conduct for longer than a predetermined continuous period of time. A latch receives the fault signal and responsively produces a blocking signal.  An interrupt circuit receives the blocking signal and responsively controllably blocks power from the motor power supply to the electrical motor.  Each of the timing, latch, and interrupt circuits is adapted to operate directly from the motor power supply and independent of any intermediate logic power supplies or associated logic devices.

Abstract: K. M. Clark 2-1 ELECTRODE ARRANGEMENT FOR LENSING               ABSTRACT OF THE DISCLOSURE A   system   is  provided  for  positioning  a  pair  of electrodes  on  either  side of the end portion of an optical fiber  extending  through  a  contact,  to  establish  an arc through  a cross-aperture in the contact and across the fiber to  melt  the  fiber into a lens, which assures close control of  the arc  and  which prolongs the life of the electrodes. The  tips  of  the  electrodes are positioned to lie slightly within   opposite   ends  of  the  cross-aperture,  to  avoid establishing  an  arc  between  the  electrodes  which passes around  the  contact  instead  of through the cross-aperture. The  electrodes  are  spaced  apart  by  at least about eight times  the  diameter  of the optic fiber, to avoid deposition of  vapors  from  the heated optic fiber onto the electrodes. The  cross-aperture extends to the tip of the contact, so the contact  can  be moved along its axis to a position where the electrodes lie on opposite sides of the fiber end portion.

Title: Automatic discharging trough for a weighing machine
Inventor: GUARDIOLA AGUSTIN D
IPC: G01G19/393
Filed: 1988-02-26
Granted: 1992-03-24
Abstract: ABSTRACT          A trough has side walls tiltable around a shaft, which is horizontal and disposed radially relative to a rotational axis for a plurality of troughs arranged in a circle. The shaft is supported as a cantilever. Linkage mechanisms connect the tiltable side walls to a vertically displaceable member. When the displaceable member moves upwardly, the side walls swing outwardly to discharge the contents of the trough. When the displaceable member moves to its lower position, the side walls come together to close off the bottom of the trough. When the trough is closed, the linkage mechanism is in an overcenter locked condition, whereby the weight of produce in the trough resting on the side walls cannot displace the side walls to the open position.

Abstract: MANAGEMENT OF CRYPTOGRAPHIC KEYS   ABSTRACT    A method for simplifying key management in situations where unique cryptographic keying relationships are required end-to-end between pairs of parties and a symetric encryption algorithm is to be used.  It is useful in cases where the parties come from disjoint subsets of the total population of parties.  The method provides some of the characteristics of a public key crypto system (PKS) utilising the public identities of the parties as part of the key, but lacks the property of PKS which allows a party to independently generate a secret key which is known only to that party.

VAN DEN BROECK  MIRIAM H. J. M. VAN LOON                       ABSTRACT An easy-open/reclosure device intended to be attached to the top lid of a container having an upstanding peripheral rim. The device includes a base portion and a moveable portion preferably hingedly attached thereto. The base portion has a dispensing aperture, a depending flange encircling the aperture, and a deformable pouring lip/drain surface. The moveable portion has a depending plug member which is shaped complementary to the base portion's aperture for reclosing the container. When the device is applied to the container, the base portion's depending flange is pushed through a prescored or pre-cut aperture in the container's top lid. In applying the device to the container, the container's peripheral rim bends the base portion's deformable pouring lip/drain surface upward and inward such that it assumes an inclined, trough-shaped configuration. This resultant shape provides an excellent surface for both channeling product up and over the container's peripheral rim when the container is tipped as well as for channeling any residual product remaining on this surface back into the container when it Is returned to its upright position.

Abstract: ENVIRONMENTAL POSITION ACTUATOR APPARATUS HAVING      LOAD RESPONSIVE LIMIT CONTROL APPARATUS            Abstract Of The Present Invention A position actuator includes a motor driven low efficiency lead screw with a follower moving in parallel relation to a valve coupler of a valve shaft and a switch operator of a force/torque limit unit.  A lever is pivotally coupled to the follower, coupler and the operator.  The lever pivots about the operator to move the valve coupler at a valve limit.  The coupler cannot move and the lever pivots about the coupler to move the operator and actuates a switch to signal an alarm and/or another controller.  The limit unit includes an elongated coil spring having a low spring rate within a tubular housing having mounting plates for switches.  The operator passes through the spring and has retainers abutting the spring ends and the housing to provide a factory spring calibration.  The lever couplings include a lever opening with spaced knife-edges to provide low friction engagement.  In a damper control, limit unit is mounted to a driven sector gear and a lever is secured to a damper shaft. At limit condition, the shaft cannot move and sector gear movement moves the operator to actuate the switch.  A linear actuator may be connected directly to the operator for in-line movement.  The limit unit provides precise identification of the actuator movement and may provide end limit signals for initializing a stepper motor control and/or a constant speed motor control.
